We designed an interleaved-TR sequence for simultaneous flow rephased/dephased imaging. And by using subtraction method by self-squaring the images prior to the subtraction, not only the artery/tissue contrast is maintained or enhanced relative to linear subtraction, but also the venous signal is greatly reduced, generating MRA result with minimized venous contamination.
